Hi,I totally agree with you... but this is not something we could solve without Debian maintainers and active support from our community, or, in other words: this is not our decision.
If you -or any member of the community- can help us to go back to Debian, we are going to support your work.
One of the main reason I'm working on 'unofficial' packages is that newest syslog-ng is not part of Debian/Ubuntu...Note that these unofficial packages is my own private playground, for myself (yes, I'm using syslog-ng on my machines...), maybe totally useless for you, but why not to share with community?
